Abstract
Embolic protection filtering devices and methods for making and using the same. An example filtering device includes a filter wire, a filter including a filter loop coupled to the filter wire, and a filter membrane coupled to the filter loop. A plurality of cam members may be coupled to the filter loop. Alternatively, the filter loop may include a plurality of strut members coupled thereto. The cam members and/or the strut members may help to stabilize the longitudinal position of the filtering device within a body lumen.
Claims16
An embolic protection filter, comprising:
- an elongate shaft having a proximal end region and a distal end region;
- a filter coupled to the distal end region of the shaft, the filter including a filter loop disposed about the shaft and a strut region extending between the filter loop and the shaft;
- a filter membrane coupled to the filter loop, the filter membrane having a plurality of openings defined therein;
- and
- a first cam member coupled to the filter loop, the first cam member being configured to move radially outward relative to the filter loop when the shaft is moved in a first direction;
- and
- a second cam member coupled to the first cam member, the second cam member being configured to move radially outward relative to the filter loop when the shaft is moved in a second direction that is opposite the first direction.
